createBitset()

template<size_t N>

std::bitset< N > semf::BitsetUtility::createBitset ( const uint8_t  data[], size_t  dataSize, size_t  firstBit  )

static

Copies a part of an array into a bitset.

Template Parameters

Number

of bits in the bit set.

Parameters

data	The array with the data.
dataSize	The size of the data.
firstBit	The first bit to be copied into the bitset.

Returns

The bitset with the bits.

insertBitsetInBuffer()

template<size_t N>

static size_t semf::BitsetUtility::insertBitsetInBuffer ( std::bitset< N >  bitset, uint8_t  buffer[], size_t  bufferSize, size_t  firstBit  )

static

Insert a bitset in a array.

Template Parameters

N	Number of bits in the bit set.

Parameters

bitset	The bitset which should be inserted into the array.
buffer	The array in which the bitset is stored.
bufferSize	The size of the buffer.
firstBit	The position in which the bitset is stored in the array.

Returns

The number of bits written into the array.

parityIsOdd()

template<size_t N>

bool semf::BitsetUtility::parityIsOdd ( std::bitset< N >  bits )

static

Returns the parity of bits in a bitset.

Template Parameters

Number

of bits in the bit set.

Parameters

bits	The bits for which parity is to be calculated.

Returns

true if ther parity is odd.
